Within hours of Ashton Kutcher confirming he’d signed on to “Two and a Half Men,” Charlie Sheen weighed in with kind words for the “No Strings Attached” star but still predicted the CBS hit would flop in the ratings.

"Enjoy the show America,” he said before leveling another dig at his ex-boss, Chuck Lorre, and other suits.

Charlie Sheen's Highs and Lows

“Enjoy seeing a 2.0 [rating] in the demo every Monday, WB," he said. "Enjoy planet Chuck, Ashton. There is no air, laughter, loyalty, or love there."

Earlier, Kutcher made a preemptive effort to stay on Sheen’s good side in an official statement about his new venture.

"I can't wait to get to work with this ridiculously talented 2.5 team and I believe we can fill the stage with laughter that will echo in viewers' homes," said Kutcher in a press release. "I can't replace Charlie Sheen but I'm going to work my ass off to entertain the hell out of people!"

Cast Aside: Actors Who Almost Had the Part

Kutcher had teased the announcement on his Twitter page Thursday evening, writing, "what's the square root of 6.25?" (That's 2.5 for those too lazy to look it up).

He'll bring a devoted, young fanbase to "Men," according to The Hollywood Reporter. Long before Charlie Sheen discovered the joys of tweeting, Kutcher boasted millions of followers on Twitter. Speaking of millions, there are talks that Kutcher will be getting a "huge payday" to join the CBS show, The Hollywood Reporter said.

Embattled show creator Chuck Lorre also weighed in on the announcement.

"We are so lucky to have someone as talented, joyful and just plain remarkable as Ashton joining our family," he said in a statement. "Added to that is the deep sigh of relief knowing that our family stays together. If I was any happier, it'd be illegal."
